FUEL HANDLING

Fuelmix

IMPORTANT! The chain saw is equipped with a two-stroke engine and must always been run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

!Always provide for good ventilation when handling fuel.

Gasoline

This engine is certified to operate on unleaded gasoline.

• Use good quality unleaded gasoline.

• The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 so- called “knocking“ can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown.

When working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

For the best results use HUSQVARNA two-stroke oil, which is especially developed for chain saws. Mixing ratio 1:50 (2%).

Never use two-stroke oil intended for water cooled outboard engines, so-called, outboard oil.

Never use oil intended for four-stroke engines.

Mixing

Always mix the gasoline and oil in a clean container intended for fuel.

• Always start by filling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline.

• Mix (shake) the fuel mixture thoroughly before filling the saw’s fuel tank.

Do not mix more than max. one month’s supply of fuel.

If the saw is not used for some time the fuel tank

should be emptied and cleaned.

• This engine is certified to operate on unleaded gasoline.

The following applies to saws with catalytic converter

Petrol

Always use high grade unleaded petrol (minimum octane rating 95). Leaded petrol will destroy the catalytic converter and it will no longer serve its purpose. The green fuel cap on saws fitted with catalytic converters means that only unleaded petrol can be used.

Two-stroke oil

For best results and performance use Husqvarna two-stroke oil, which is specially formulated for chain saws. Mixture 1:50 (2%).

!WARNING!

The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when handling the saw near flammable substances or vapours.
